In the container of an electric blender or food processor, process cookies, in small batches, until finely crushed.

Remove 6 cherries from cherry filling; reserve for garnish.

To assemble dessert, spoon 2 tablespoons ricotta cheese mixture into each of six (8-ounce) parfait glasses. Add 2 tablespoons cookie crumbs to each glass; top each with 2 tablespoons cherry filling. Repeat ricotta, crumb and cherry layers. Finish each serving with an equal portion of the remaining ricotta cheese mixture.
